Abstract
A method for managing the capture of packets in a computing system comprises maintaining a buffer tail pointer in a memory of an instruction executing device, receiving a series of packets at an instruction executing device, for each received packet prepending a header comprising a packet length and a packet pointer set to a current value of the buffer tail pointer, determining a next free memory location by adding the current value of the buffer tail pointer to the length of a previous packet identified by the buffer tail pointer, temporarily writing the packet and prepend header to the next free memory location in a circular packet buffer in a memory coupled to the instruction executing device, and setting the buffer tail pointer to the next free memory location.
